High in the foothills of the Himalayas, after an hourslong trek up the hillside, Lisa Philippone and her fellow researchers finally reached the village. “It was just so crazy because you’re hiking, it’s so steep, it’s pouring rain all over us, and we get to the top and this little old lady is there, and she’s cooking on her stove,” remembers Philippone, a master’s student in the Duke Global Health Institute.
